Abstract

Behavioral specifications are often employed for modeling complex systems at high levels of abstraction. Failure conditions of such systems can naturally be specified as assertions defined over system variables. In that way, such behavioral descriptions can be transformed to imperative programs with annotated failure assertions. In this paper, we present a scalable source code based framework for computing failure probability of such programs under the fail-stop model by applying formal methods. The imprecision in the estimation process resulting from coverage loss due to time, memory bounds and loop invariant synthesis, is also quantified using an upper bound computation. We further discuss the design and implementation of ProPFA (Probabilistic Path-based Failure Analyzer), an automated tool developed for this purpose.
